Comparison of Acceptable Noise Level Generated Using Different Transducers and Response Modes

Table 3

Values of the mean, standard error (SE), and range for MCL, BNL, and ANL averaged across all the subjects for each method. The significance level was set at .

Method	MCL value (dB HL)			BNL value (dB HL)			ANL value (dB)
	Mean	SE	Range	Mean	SE	Range	Mean	SE	Range
LS	36.83	1.33	25.33~48.00	37.30	1.47	27.33~55.33	−0.47	0.57	−7.33~3.33
LA	38.27	1.32	29.33~50.00	38.27	1.32	30.00~54.67	−0.53	0.58	−4.67~4.00
ES	44.10	1.81	31.33~60.67	44.13^#	1.91	29.33~64.00	0.00	0.63	−4.67~6.00
EA	44.60	1.45	36.67~58.67	44.67^#	1.54	35.33~63.33	−0.10	0.60	−5.33~4.00

Values of MCL were significantly different from each other. Values of BNL were significantly different between the ES and EA methods. Values of BNL were significantly different between the LS and LA methods.
